Recently I've been watching the ending to this fine game a fair number of times. Now I'm quite the hard-ball type, but even I well up everytime I watch it. I have the FFX soundtrack on my Winamp when I'm working on writing/coding/whatever and need something in the background. When the ending music gets shuffled in I almost immediately have the urge to go watch this ending. I have a real appreciate of the character of Tidus, as demonstrated here.
This could very well be the best ending in a Final Fantasy. Discuss.
